Title: Removed what seems to be a duplicated function to get a handle from a userid.

Removed function qa_post_userid_to_handle in file qa-app-posts.php as it seems the logic was also present in qa_userids_to_handles in file qa-app-users.php but just received a different parameter.

Also added the equivalent function to the existant one that receives only one userid instead of an array.
